Everyone — this is a photo taken in a mirror. So his LEFT side is facing toward us and he is holding the phone with his RIGHT hand. Josh has a giant anchor tattoo on his LEFT side (seen in non-mirror-image photos). The tattoo ought to be front and center. Go do it yourself in the mirror.

Re: grosky – this photo is said to be from 2011 or so. And if I'm not mistaken, Josh didn't get his anchor tattoo until around March or April of 2012. So it still could be him. And if you don't hunk so, just look up when he got his anchor tattoo online.

Saw the naked pic. Seems like that dude had a tatoo on his pelvic bone. Some fan posted Josh's pics from Hawaii with his shorts pretty low. No tatoo on his pelvic bone area. So I think we can safely say that isn't him.

Zayn previewed the duet by posting a black and white pic of himself with Swifty on his Instagram -- but hey, she is bestiez with his girlfriend Gigi Hadid, so it wouldn't be unusual that they hang out... But collab?!
